There's got to be something wrong, if a sleved went bad. The only thing there that makes sense is; all three (3) blocks had too many bad miles on them, and they were suffering from cavitation in other parts. We have to look a things with logic. I have heard that 150K miles without treatment is a point when cavitation begins. I was under the assumption that cavitation happened to the cylinder sleeves. And if someone puts in a new sleeve, and it fails within a short period of time; well a few things come to mind. One, poor workmanship is a possibility; Two, cavitation happened to another area of the block and/or heads; and, Three there was a problem with the chemical balance, i.e. the block(s) were so badly corroded the cavitation issue was greatly amplified.
I just know that, under the laws of physics something (new with no corresive issues) does not go bad, unless there was another element involved which was either overlooked, or ignored.

They screwed the sleeve job according to Dave. It had nothing to do with cavitation. On all the blocks he gotten from them, the sleeves moved in the block!!! They obviously had or are having issues sleeving these blocks correctly. When the sleeve moves in the block, you can imagine the damage it will do.

do you know where the thread is that explains all this?
thanks,

The installation of a sleeve needs to have an interferance fit. Its called the press. Sometimes on large diameters the fit will be as much as 6 thousands. So our sleeves should have at least a 1 1/2 to 2 thousands fit. I personally prefer a 3 thousands press fit. This all means the bore in the block is that much smaller than the sleeve. These sleeves will "shrink" easily in liquid nitrogen. If the shop doesn't have that find another shop. Don't let them tell you they use superglue or red loctite to "hold them in the bore". Freezing them in the refrigerator wont work either. Dry ice is ok but I don't feel it gives enough shrink fit. Once the sleeves are in the block they need to be held inplace with allthread and a strongback. Otherwise they can "walk out" as they normalize in temp to the block. I have plenty more information on sleeving a block correctly if its needed.
